SASH-HOLDER.

Specification of Letters Patent.

Patented sept. 18,1906.

Application filed October 24, 1905. Serial No. 284,228.

To all whom it may concern:

Be it known that I, MORRISSON J. BAR- NETT, acitizen of the UnitedStates, residing at San Francisco, in the county of San Francisco andState of California, have invented certain new and useful Improvementsin Sash-Holders, of which the following is a specification.

This invention relates to improvements in sash-holders, the object ofthe invention being to provide a device of this character which shall becheap and simple in construction, convenient in operation, and durablein use.

In the accompanying drawings, Figure lis a plan view of the device inits operative position, the upper sash being shown in section. Fig. 2 isa similar view, the device being shown open. Fig. 3 is a verticalsection, on an enlarged scale, on the line 3 3 of Fig. 1. Fig. 4 is a toplan view of the bottom plate. Fig. 5 is a ottom plan view of the same.Fig. 6 is a cross-section on the line 6 6 of Fig. 4. Fig. 7 is across-section on the line 7 7 of Fig. 5. Fig. 8 is a perspective view ofthe plate and lever detached from the sash, the pressureblock beingremoved.

Referring to the drawings, 1 represents the lower sash, and 2 the uppersash of a window. Upon said lower sash is secured, by means of a screw3, the plate 4, which has formed therein at one corner two series ofteeth 5 6, the series 5 extending outwardly from one side of the plateand theseries 6 from the other side. By this means of construction theplate may be used either side up, thus permitting the lock to be usedeither righthanded or left-handed. If the side seen in Fig. 4 beuppermost, then the series of teeth 5 will be used, as shown in Fig. 8;but if it be desired to turn the pressure-lever in the other directionto clamp the sashes then the plate will be inverted and the series ofteeth 6 will come into operation. On said plate is pivotally secured bythe same screw 3 which holds the plate to the sash a pressure-lever 7,which is formed all in one piece and has at the outer end a finger-piece8 and at the other end is providedwith a box-like receptacle 9 toreceive a block 10 of any suitable yielding substance or composition, asrubber or fiber.

With this construction the operation is as follows: To secure the sashestogether, the operator presses the finger-piece to turn the lever fromthe position shown in Fig.2 to that shown in Fig. 1, the rear edge ofthe plate then passing in succession over the teeth 5 until the block 10of yielding material is firmly pressed against. the sash. Said block isheld firmly to the sash by said teeth. In order to unlock the sashesfrom each other, the outer end of the lever is lifted slightly by thefinger-piece, so as to clear the teeth, and is then permitted to returnto the position shown at Fig. 2. It will be observed that the main stemof the lever is concaved at the underside, as clearly shown at 11 inFig. 3, the objectbeing to permit the lever to clear all the succeedingteeth of the series when its advancing edge has cleared any one tooth.It will also be observed that the lever-handle has a portion flat on theunder side, as shown at 12, to facilitate the raising of the rear end ofthe lever, as well as a portion which is flat sidewise, as shown at 13,to facilitate the lateral movement.

The device is very simple and inexpensive to manufacture, consisting ofonly two main metallic parts, both of which can be easily stamped outfrom sheet metal. It is also convenient in use and can be used eitherright-handed or left-handed. It is also very durable, as the yieldingblocks can be renewed from time to time. Moreover, by providing a seriesof teeth the device is selfadjusting, either for accuracy of attachmentor for wear of the pressure-block, since one of the series of teeth willalways be found to 7 provide a proper support for the block whenpressing against the sash. The construction of the receptacle-for thepressure-block is also advantageous, as said receptacle surrounds theblock on all sides except the front, and therefore holds it very firmlyand immovably in position. The receptacle itself is also well supportedagainst backward thrust by its connection with and arrangement upon theend of the lever.

I- claim 1. In a device of thecharacter described, the combination of aplate adapted to be secured to a window-sash, a lever swinging on saidplate about a pivot at right angles thereto,and a pressure-block carriedby said lever and adapted by the movement of the lever to be broughtinto contact with the other window-sash, said plate being provided witha series of stops preventing the return movement of the lever,substantially as described.

2. The combination of a horizontal edge of a window-sash, a platesecured thereto, a lever pivoted at one of its corners on the plate toswing horizontally on said corner, said lever having a handle for soswin ing the same, and having at its end next the other sash of thewindow a vertically-extending receptacle for a pressure-block, and apressureblock therein, the plate having a catch or stop lookingthe'lever in the desired tion, substantially as described.

3. In a device of the character described,

posithe combination of a plate adapted to be see cured to a window-sash,and having two se ries of stops formed thereon, extending outward onopposite sides thereof, and a lever pivotally attached to said plate andswinging 4. In a device of the character described,

the combination of a plate adapted to be secured to a window-sash andhaving a series of stops extending upwardly therefrom, and a leverpivotally secured to said plate and adapted to swing in a plane parallelwith the plate, the lower edge of the lever being adapted to be engagedby any one of the series of stops, the under side of the lever beingconcaved to permit the main body of the lever to pass freely over saidstops, and a pressureblock carried by said lever, substantially asdescribed.

In witness whereof I have hereunto set my.

hand in the presence of two subscribing witnesses.
